“…With the evolving knowledge of the complex variable anatomy, surgeons began to adapt individualized surgical techniques that will suit the different pathological variants. The procedures include: (1) simple atrioseptopexy, 24 (2) mobilization of the atrial septum, 25 (3) creation of flaps from the right atrial wall, 26-27 (4) preservation of the cavoatrial junction anastomosing the transected SVC to right atrial appendage, 9 (5) circumferential anastomosis of the right atrial appendage to the SVC preserving the cavoatrial junction, 2 (6) augmentation of the Warden’s repair using pedicled pericardium, 28 (7) modified Warden’s procedure with a right atrial appendage flap, 2 (8) single-patch or double-patch techniques using various synthetic or autogenous tissue patches, through a right atriotomy, traversing the cavoatrial junction, 8 (9) longitudinal or transverse transcaval incisions, with or without terminal SVC augmentation, 4,7 -12 (10) Cooley’s V-Y plasty, 17 (11) transverse superior venacavotomy and posterior placement of a glutaraldehyde-treated pericardial patch, 29 (12) transcaval repair using a butterfly shaped patch, 7 (13) lateral caval flap repair with concomitant autologous pericardial patch, 30 (14) single-patch fold-back technique for augmentation of the SVC, 31 (15) superior caval enlargement by right atrial edge rotation, 32 and (16) modified cavoatrial anastomosis using a posterior right atrial flap and anterior onlay pericardial patch. 28 A novel transcatheter approach was described in 2014 in cases of superior sinus venosus defect with PAPVC with limited application.…”
